    摘要： In a radiation generating apparatus of the invention, a radiation tube having a cathode for emitting an electron and an anode for generating a radiation by an irradiation of the electron emitted from the cathode is enclosed in a housing container filled with an insulating liquid. The apparatus has a mechanism in which a voltage for allowing the insulating liquid to flow can be applied between the cathode and the anode in a state where the cathode does not emit any electron. Even when the generation of the radiation is stopped, the insulating liquid can be efficiently sufficiently cooled without providing mechanical stirring means, and a high reliability is obtained even for intermittent use.

    摘要： The present invention provides an X-ray generating tube including a transmission target having a minute focal spot. The X-ray generating; tube includes a transmission target having a first surface and a second surface opposite to the first surface, the first surface being irradiated with an electron beam, and the target radiating X-rays from the second surface; an electron emitting source emitting the electron beam in such a manner that the electron beam obliquely enters the first surface; and a tubular forward shield member located at the second surface side of the target to define an extraction angle of an extracted X-ray beam. The forward shield member is disposed such that a central axis of the electron beam and a central axis of the X-ray beam whose extraction angle is defined are located at the same side with respect to a virtual normal plane perpendicular to the first surface and a projection central axis that is a projection of the central axis of the electron beam to the first surface.

    摘要： In a multi-source radiation generating apparatus including a plurality of combinations of a cathode and a target, an extraction electrode is disposed for a plurality of cathodes in common. When a potential of the extraction electrode is constant, potentials for the cathodes are selectively switched between a cutoff potential which is higher than the potential of the extraction electrode and an emission potential which is lower than the potential of the extraction electrode.
